Piazza has called area veterinarians, animal shelters, adoption agencies and posted lost dog advertisements on Craigslist, but he has had no luck.

"I've been doing what I can to find him," Piazza said.

On Craigslist, there seems to be a trend of missing huskies and dogs, Piazza said. Several dog owners have reported their dogs missing in similar circumstances on the website.

Currently, Piazza's brother is keeping track of all huskies posted on Craigslist -- calling all of the advertisements for huskies that are found or for sale that do not include a photo.

Since he began his search, Piazza has read many horrific stories of dogs being stolen for dog fighting. He doesn't believe this is what happened to Rico.

"I think someone probably took him to sell him for cash ... but I don't know who," Piazza said. "... I think I've pretty much exhausted everything I could do to find him."

Joanie Toole, administrative supervisor of Oakland County Animal Control, said there are various reasons a dog might be stolen.

"I know a lot of cities they tend to get a lot of missing dog type of things, but there could be various reasons why people would steal a dog, it could be a dog fighting ring, it could be someone who is mad because of continuous barking ... or maybe it just climbed the fence," Toole said.

Since Rico has been gone, life for Piazza and Mia hasn't been the same.

"Regardless of who they are ... whoever it is, I just want them to know it's been a source of pain in my life," Piazza said.

All Piazza is asking for is his dog back, even if it is from the person who took him -- no questions asked. He is offering a $500 reward to be reunited with his dog.

"We (Mia and I) would both just really like to have him back," Piazza said.

If your dog is missing, you should visit Animal Control located at 1700 Brown Road in Auburn Hills. If you believe the dog was stolen, you should call your local police department.
